I would like to support cross-compilation of nginx, but I would 
like to see something more extensible, not configure arguments to 
specify anything.  I.e. some configuration file and/or defaults 
for type sizes, ngx_feature_run=yes tests and so on.

First step would probably be to audit ngx_feature_run=yes tests 
and remove "yes" in cases where it's not needed/can be handled at 
runtime.
